Kalshi’s year-end S and P 500 bracket edges up to nine cents

The bracket for the S and P 500 finishing between 7,200 and 7,399 on December 31 traded 1,284 contracts in 24 hours on Kalshi with 240,000 contracts in open interest, according to the PredictionMarketPicks snapshot at 2:05 AM EST on November 1.

The Kalshi contract covering an S and P 500 finish between 7,200 and 7,399 on December 31 was priced at nine cents, a one-cent increase over 24 hours, according to PredictionMarketPicks.

Trading activity and outstanding positions

The bracket recorded 1,284 contracts traded in 24 hours, according to the outlet’s snapshot at 2:05 AM EST on November 1. Open interest stood at 240,000 contracts.

Those figures describe different aspects of activity: volume measures contracts traded during the reporting window, while open interest measures outstanding contracts. The snapshot does not show how open interest changed over that period.

A narrow view of the year-end market

The material was published on Nov 1, 2026, at 2:30 AM ET. Its pricing and activity figures concern this specific December 31 range, rather than the full distribution of possible S and P 500 outcomes.

No prices for neighboring brackets or broader market totals were supplied. That limits comparisons of this range’s pricing and trading activity with other year-end outcomes.

What it means for prediction markets

  • The move to nine cents marks a one-cent increase in the bracket’s price over 24 hours; it does not establish a longer-term trend.
  • The 1,284 contracts traded and 240,000 contracts in open interest provide distinct measures of activity, not a count of individual traders.
  • Without neighboring bracket prices, the snapshot cannot establish which December 31 range the market considers most likely.
